[obm-l] Teoria dos Números - Tranformação Linear
Alguém pode me ajudar nessa..
Show that for every linear transformation
/
| 2’ = ax + by ad - bc = n(# 0)
| y’ = cx + dy
\
a unique set of integers A, B, C, P, Q, R, S exists
such be expressed as a result of the transformation
/
| x’ = Ax” + By” AC = |n|
| y’ = cy O <= B < A
\
together with the transformation
/
| x” = Px + Qy PS - QR = +- 1
| y´ = Rx + Sy
\
Hint. Make use of a canonical basis (A, 0), (B,C) for
module L2 generated by the vectors w1 = (a, c), w2 =
(b, d).
